What are the costs of a family law case?

[3] The Ontario Court of Appeal in Mattina v. Mattina, 2018 ONCA 867 set out that modern costs rules are designed to foster four fundamental purposes: (1) to partially indemnify successful litigants; (2) to encourage settlement; (3) to discourage and sanction inappropriate behaviour by litigants and; (4) to ensure that cases are dealt with justly under subrule 2 (2) of the Family Law Rules (all references to the rules in this decision are to the Family Law Rules).
